Wow Jerry! Let me see if I get this right:

You drove 96,000 miles in your H2. At a generous estimate of 16mpg, you used 6,000 gallons of gas. A Prius owner, at about 48mpg, would have used 2,000 gallons of gas. So you bought an extra 4,000 gallons of gas (conservatively) at an average price of, say, $2.75 a gallon. That's about $11,000 extra. Not to mention the massive depreciation hit you've taken recently (your KBB Private Party Value has sunk to the vicinity of $15,000).

I'm glad your tires are holding up.
